LED Panel 225 (blue+red)

Red/Blue Mixed Light-emitting diodes, or LEDs has been around since the early 1920s, but have only recently been used in hydroponics gardening as grow lights.
This type of grow light has many advantages over fluorescent and metal vapor lights, and no real downsides other than the initial expense.
While they do cost more in the beginning, LEDs are considerably cheaper in the long run because of their long life span (average life is about 100,000 hours, compared to an average 15,000 hours for other types) and energy efficiency (energy consumption is about 10 to 20% of comparable fluorescents and metal vapor lamps). In addition, LEDs are cooler, thus eliminating the need for fans and elaborate ventilation systems.
